The drain is frozen as you suspect. Remove whatever you need to in order to get to the rear wall of the freezer to access it. Remove the rear wall and the drain hole is centered just behind it on the freezer floor. Use a spray bottle or hair dryer to remove the ice that is there. Do not chip at the ice with anything sharp. The drain is clear when water runs down it. You may need to blow thru the drain to clear it if the ice is cleared and the water still will not drain. This is nothing complicated, it just takes time and effort to do..
